# Pasquale Cirillo and Nassim Nicholas Taleb
**Domain:** Statistical risk research
**Doc Type:** Developed Collaboration Node
**Maturity:** Developed
**Collection:** [[collections/Gamification|Gamification Collection]]
## Definition
**Pasquale Cirillo and Nassim Nicholas Taleb** developed a statistical analysis of violent-conflict fatalities using fat-tail methods and a transformation for variables with a remote finite upper bound. Their work challenges confident claims that recent declines establish a durable “long peace.”
## Significance
The collaboration supplies the collection's quantitative warning: catastrophic violence cannot be evaluated with intuitions suited to normal variation. Tail uncertainty and data quality must remain visible when institutions claim that an enclosure has made extreme war unavailable.
